Which process is pegging the CPU?

We have two nodes which are serving PHP webpages with PHP5-FPM. Both Nodes are configured with drbd in dual primary mode.

In our tests, if one of these two nodes get 10-20 Pagerefresh's at the same time, the CPU are 100% in use.

For these 10-20 Pagerequests the server are 1.5 minutes busy.

Without OCFS (harddrive is formatted with ext4) for the same 10-20 requests, it tooks only 0.1 Seconds to complete.

We only see a long running PHP Process which get timeouted sometime with '30 seconds exceeded for including a file' . We tried mounting the ocfs2 device with 'noatime, nodiratime, data="" but it didn't helped.

does someone has a tip for us ?

(If we use ocfs2 with icsci, there are no changes)

thanks a lot!
